If it came out of your Celica, it's an HB4 also called a 9006. The High beams use the HB3 bulb also called the 9005.
If you have trouble finding bulbs, check out
http://www.powerbulbs.com, they've got free international shipping and you get free w5w bulbs (park lights) with most orders. I got Philips BlueVision bulbs from them years ago - they're a nice white light (not the fake blue look the cheap supercheap bulbs have), good illumination and are still going strong.
Remember when you put them in not to touch the glass part of the bulbs - the oils on your skin don't play nice with the bulb once it gets hot
